Tol/lll ivzoi/z fit may @muera Be it known that I, Nlononws Willman, acitizen of the United States, and a resident of Canton, in the county ofFulton and 'St ate of Illinois, have invented' certain new and lusefulImprovements in Draft Devices forlVheeled Gang-1lows; and I, do herebyvdes elare that the followingis a t'ull, clear, and exact descriptionthereof, reference beingr had to the accompanying drawings, and to thecharacters of reference marked thereon, which form a part of thisspecitication.

This invention relates to improvements in equalizing drait devices formotor drawn gang plows arranged to avoid pullingr the .plow outof thestraight line of draft 'upon illustrated 1n my prior application tor YUnited States Letters latent, Serial Number 607,312, tiled llebruarySth, 1911, ot which the present application is 4a division.

' Such parts of thegeneral construction ot' the plow only as arener-.essarv to an understanding ot the present invention are hereinillustrated, butl it will be understood that the invention, is notlimited to plows otA this or an)7 particularconstruction.

The frame ot the plow shown in Fig'. `l is an oblong rectangular tramecomprisingr the front and rear members l5 and It, re-

Spectively,'and the end members 17 and lh.

The said trame comprises a. plurality ot sec tions which are jointed orhinged at 'lil in the 4manner .shownin my aforesaid application, topermit the plow to adapt itsclll to uneven ground. The rear member maysupport a series oi disk plows 2O in a'mam'icr illustrated in myaforesaid prior applica tion and said plows are adaptedto be raised andlowered by means which constitute. no part of the present invention andneed not be hcreinturther described. The front end of the trame issupported on the furrow wheel and the land wheel 22.253,respectively.mounted on stub axles that are piroted at 4 at the il'orward end otl thetrainenl and said stub axles are connected b tlu` linh f to canse thcaxles and wheels to swingt; to gelber. 'l`hc wheel 22 is a l'urrow wheelto travel in the i'url'ow, and the whccl l travels on tht` land. 'therear end ol` thc trameis supported b'v a turrow wheel 't mounted on astub axlc which is pirotcd al 3T to the rrar ond olz the t'ranle. andsaid roar end ot' the .traino is supported also by a dral': reg-abatinev and supporting' roller it that travels on the land and isccntrall).vv pivo'tcd to a brachet or extension lfl at thc rear end ol'the plow traine. llho said rear `t'urrow wheel Ztl and thc di'at'tl-'eg'ulating and supporting roller 2H are connected b.\' a linh Il() locause said supporting; members to swing; in unison. as shown in VFie'.l. 'lhe plow traine is supported at points intermediate tht` l'ront andrcai' ends thcrcot' on other drat't rcg'ulatingr and supporting` rollersl, tt inadc lilo` tbc dral'ty regulating'and supporting' rollers shownin in v a't'orcsaid application and cen trally piroted to oblique tramemein-ben` rtf. il?) ot' the plow traine. it?.
